Can't use cards in Terminator? [Answered]

Is that normal, I mean, I eliminate opponent on my turn and I get their cards but the game doesn't allows me to use it right away? Just now it happened, I started turn and selected my 3 red green blue cards, then I eliminated green and got his 4 cards (red green blue green) but the game doesn't even show "use cards"... i had a plan and now its over.... 
is that normal in terminator games or am I victim of the system?
